What is a potential risk when operating a UAS at high altitudes?

Operating a UAS at high altitudes introduces several challenges, one of the most significant being the higher potential for signal interference. As altitude increases, the density of the atmosphere decreases, which can affect the radio signals used for communication between the UAS and the remote pilot.

Additionally, at higher altitudes, the UAS may encounter a range of unexpected obstacles, including weather phenomena that can interfere with signal transmission. Increased distance from ground control can also lead to reduced signal strength and potential loss of control. This is particularly critical because maintaining a reliable communication link is essential for safe UAS operations.

While options such as increased visibility or improved stability might seem advantageous, they do not directly address the primary risks associated with high-altitude operations. Similarly, longer flight times can occur due to the energy efficiency of high-altitude drone flight, but they do not mitigate the critical risks brought about by signal interference. Therefore, recognizing the potential for higher signal interference at increased altitudes is vital for ensuring safe and effective UAS operations.
